JOSEPH T. PBOWS, OF CYNTHIANA, KENTUCKY BEDSPRING Application filed August 30, 1928 Serial No. 303,059.

This invention relates to an adjustable bed spring device.

It is aimed to provide a generally improved construction which may enable the occupant sto occupy and have the back supported in a sitting posture and as well be adjusted to provide elevation at the head to take the place of pillows, bolsters and the like, thus adapting the device particularly for use by inva- 'lids, the convalescing, and the like whether in homes, hotels, hospitals, sanitarlums or otherwise.

A very important object is in enabling pillows and bolsters to be dispensed with so as to save the expense and labor incidental to laundry work required thereby.

Various additional objects and advantages will be pointed out or become apparent from a consideration of the description following 6 taken in connection with accompanying drawings illustrated operative embodiments.

In said drawings Figure l is a perspective View of a spring made according to one form of the invention, Figure 2 is a detail sectional view taken on the line 2-2 of Figure 1,

Figure 3 is a detail elevation of a part of the anchor rod and connection of the spring 40" rising from the side bars 10 at the head.

Bracket arms 13 are pivotally mounted at 13 on the upper ends of the vertical bars or posts 12 and terminate in hooks 14 at their free ends, and are also provided with supplemen- 45" tal hook members 1 1 15 designates latch braces pivotally secured at 15 to the arms 13 and each of said latch braces is provided with a notch 15 to engage a pin 12 on each of the posts 12 to hold the arms in horizontal posi- 50 tion, as shown in Figure 1.

Figure 4 is a detail sectional view taken A'spring support for a mattress is shown as at 16 and consists of transverse spring elements 17 fastened to the side bars 10 and longitudinal spring elements 18 fastened to said transverse spring members 17 and crossing the same and also fastened to the bar 11.

The spring members 17 and 18 that are made of steel Wire have spaced coils19 therein, and spring members 18 have extensions 20 that are bent upwardly and provided with coils 21 and have at their upper ends loops or eyelets22-to receive and be secured to one of the ends of flexible elements 35. 23 indicates loops in spacing bar 24: to receive the ends ofsprings 18 below the eyelets 22 to hold them relatively spaced. 27 indicates chains having hooks 28 on one of their ends adapted to engage coils of the springs 18 to connect them to hooks on cross bar 29 connecting side bars of the frame 10, said cross bar having upwardly extended ends 29 that are secured to'said side bars to locate the cross bar 29 below the springs. Hooks 30are adjustably connected to crossbar 29 by means of threaded stems 31 and nut 32. 26 indicates a ring on the end of each chain27 that'is slidably' mounted 011 extension20.

An anchor rod 33 may removably rest in the hooks l4 and have lugs 34 thereon to which flexible elements 35 are fastened as by means of eyelet-s 36 and which elements extend-from the eyelets 22. A guard rod 37 is carried by the rod 33, assisting in preventing detachment of the eyelets 36 and such detach-' ment is further resisted bycoiling the elements 35 around the rod 33 as is shown in Figures 2 and 3. V

VVith the parts shown in the position of Figure '1, .theoccupantmay assume a sitting posture on the spring with his back supported by the coils 2 1 of springs 18, it being understood of'course that the spring is covered with a mattress in the usual manner and that the same'may be extended over the coils 21 or a suitable covering maybe arranged over them instead. y

The rod33maybe removed out of engagementjwfith the hooks 14 and placed in engagement" with any hooks of a series of hooks 38 arranged at the back of the post 12. In the latter position, the coils 21 and associated parts may be arranged at any desired angle so that covering may be applied directly over the same bolsters and pillows dispensed with.

Inconditions where the coils 21 and associated parts of the springs should move bodily or unduly relative to the remainder of the springs, the hooks 28 are engaged in adjacent coils 19 of springs 18 and the chains 27 are fastened to the bar 29 but in other instances, such chains pass freely over the bar 29 and move with the springs.

A modified form is shown in Figures 5 and 6. In such form an ordinary metal bedstead is illustrated. The frame made up of the parts 10, 11, 12, 13, 15 and 38 are omitted and in lieu thereof, the rectangular spring frame 40 of the bed is used. The springs 18 are fastened to across bar 41 at the foot of the bed and secured to side beams 42 of such frame 40. The foot frame of the bed is shown at 43 and the head frame at 44, the latter having a series of notches 45. As in Figure 1 the head frame 44 is provided with arms 46 pivotally mounted thereon and having hook members 46. The rod 33 may selectively be arranged in the notches 45 or hooks 46 according to the angle desired for the coils 21. The bar 29 in this form has its equivalent in a similar bar 47 which is fastened at 48 to the side members 42. The other parts are similar to those of the first form.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention 1. A device of the class described comprising a frame, spring means carried thereby, a cross bar on said frame, said spring means having rods extending over the cross bar and having upwardly inclined portions to form a head, flexible elements secured to said bar and slidable at one end on said rods, said flexible elements extending across the bar and being connected at their other ends to said spring means.

2. A device of the class described comprising a frame having a main portion and an upwardly and forwardly extending portion, the latter portion being provided with hooks, an anchor rod positioned by the hooks, spring means secured to the main portion and having inclined upwardly extending portions adapted to form a head, flexible elements connecting the anchor rod to said inclined portions, aguard rod on the anchor rod through which the flexible elements pass, a cross bar on the main portion of the frame, chains secured to said cross bar and on one side thereof being slidably mounted on portions of the spring means and on the other side thereof being attached to said spring means.

3. A device of the class described comprising a frame having a main portion and an upwardly and forwardly extending portion, the

latter portion being provided with hooks, an anchor rod positioned by the hooks, spring means secured to the main portion and having inclined upwardly extending portions adapted to form a head, flexible elements connecting the anchor rod to said inclined portions, a guard rod on the anchor rod through which the flexible elements pass, a cross bar on the main portion of the frame, chains secured to said cross bar and on one side thereof being slidably mounted on portions of the spring means and on the other side thereof being attached to said spring means, and spacing bars having eyelets through which the inclined portions pass, one of said spacing bars being arranged adjacent the junction of the inclined portions with the remainder of the spring means, and the other spacing bar being disposed adjacent the top of said portions.

In testimony whereof I affix my signature.
